Used 20 ton Caterpillar Cat320gc excavator, good condition, latest model

Detailed description of Caterpillar 320GC excavator:

1. Basic parameters and performance characteristics

Tonnage and weight: It is a medium-sized excavator of 20-22 tons, and the working weight of the whole machine is 20,300-20,500 kg.

Bucket capacity: The standard bucket capacity is 1.0 m³, which can be adapted to various attachments such as rock bucket and wide bucket.

Engine configuration:

Equipped with Cat C4.4 ACERT electronic control engine, the rated power is 110 kW (about 150 horsepower)/2000 rpm, which meets Tier 3/National III emission standards.

The fuel tank capacity is 345 L, which supports long-term continuous operation.

Environmental protection and energy saving:

Compared with the old model, fuel consumption is reduced by 20%, and no urea solution is required, which meets the National IV standard and reduces the need for downtime regeneration.

The intelligent power management system optimizes fuel consumption and further reduces operating costs in economic mode.

2. Core performance advantages

Hydraulic system:

The maximum flow of the main pump is 429 L/min, and the working pressure is 35,000 kPa, providing efficient hydraulic power distribution and shortening cycle time.

Using load-sensitive technology, the flow and pressure are automatically adjusted according to the working conditions to improve the smoothness of compound movements.

Digging capacity:

The maximum digging depth is about 6,630 mm, the maximum digging radius is about 9,780-9,940 mm, and the bucket digging force is 129 kN.

The walking speed is 5.5 km/h and the rotation speed is 11.3 rpm, which is suitable for complex terrain and narrow space operations.

3. Design and operation experience

Stability and durability:

The X-type reinforced frame and inclined crawler design are adopted to reduce mud accumulation and enhance the stability of wetland and slope operations.

Key components (such as booms and dipper sticks) use high-tensile strength steel to extend service life.

Cab design:

ROPS/FOPS certified cab, equipped with air suspension seat, 7-inch touch screen and automatic temperature control system, comfortable operating environment.

Low noise design (≤68 dB in the cab), with Bluetooth radio and USB interface, improves the operating experience.

4. Maintenance and safety

Convenience of maintenance:

Daily maintenance (such as oil inspection and filter replacement) can be completed on the ground, the filter life is extended to 1000-3000 hours, and the maintenance cost is reduced by 15% compared with the old model.

Centralized filter layout and visual oil detection port simplify the maintenance process.

Safety function:

Equipped with rollover protection structure (ROPS), anti-slip ladder and electronic safety lock (PIN code activation) to ensure operation safety.

5. Market positioning and user feedback

Applicable scenarios:

Applicable to medium-load operations such as earthwork, mining, municipal construction, etc., taking into account efficiency and economy.

Multi-functional attachment adaptability (such as hydraulic hammer, grab bucket) supports diversified needs.

User evaluation:

Advantages: fuel-efficient (comprehensive fuel consumption reduced by 8-12%), smooth operation, strong durability.

Disadvantages: The price of the new machine is relatively high, and some users reported that the explosion-proof film affects the vision at night.

Comparison with similar models: Compared with the 320D series, the 320GC pays more attention to economy and is suitable for users with limited budgets but pursuing Carter quality.
